Daily Simple Interest loan calculation involves a method by which the interest on a mortgage loan is calculated on a daily basis. The loan balance is reduced on the day when the payment is reduced rather than on the day when payment is due.


Under the Daily Simple Interest formulae, the daily interest rate is given by:


Daily Rate= Annual Rate/365

Amount of interest payable each month = Number of days since last payment * principal outstanding balance * Interest Rate factor


Let's take an example where outstanding principal balance is $10000. You've sent in a payment of $170 around 30 days after your previous month's payment. Let's say the interest rate is 8.5% (the interest rate factor is .00022585)


As per the above formulae,
Interest payable each month = 30 * 10000 * .00022585 = $67.7555


Daily Interest = Daily rate * loan balance

How are you billed for a daily loan that charges daily simple interest if the loan is tied into an index that changes daily. How would you know what your actual payment would be by the due date? In trying to pay the interest early (putting more to principal),.

If your result goes beyond the precision of a penny, what happens to the rest of the numbers?

If I am due for 4/1 and if your monthly payment is 400.00, and I make 1200.00 payment in one month, what would be my next due date for a daily interest loan?

Hi Guest,

You need to contact your lender in order to know the next due date for your daily interest loan.

Thanks

I was told that conventional loans are calculated with 360 and government loans with 365.

What is correct?
Thank you.

If you have a daily interest loan would you have the typical 30 day pay window in the mortgage contarct? If so would this not be confusing?

Well, I don't think it will be confusing!! Why do you say it will be confusing??
